WILLIAM. ECK ERT, OF SYRAGUSE, NE'W YORK.` Lett/22's Patent No. 64,001,dated .April 23, 1867.

IMPROVEMENT IN PLANE IRONS.

TO ALL WIIOM IT MAY CONCERN:

Be it known that I, lVILIiIAM HENRY ECKERT, of the city of Syracuse,Onondaga county, New York, have invented a new and improved Plane; and Ido hereby declare that the followingris a full, clear, and exact4description of the same, reference being had `to the annexed drawings,making apart of this specification.

The letters used represent corresponding parts wherever they occur.

To enable others skilled in the art to make and use my invention', Iwill proceed to describe the saine, and its form when complete and readyfor use.

Figure 1 represents a `perspective view of the plane irons when pnttogether.

Figure `2 represents the cap.

Figure 3 represents a cross sectional view of both the plane irons, withthe nut and screw.

VIn the common forni ofl plane irons the screw is made to pass .directlyinto the cap, for the `purpose of holding the two -irons together. Thisform of construction involves the necessity oi" unscrewing the capwhenever the irons are separated for sharpening, or any other purposeof-separation. The object of my invention is to dispense with thisnecessity and enable the irons `to separate by simple handling.

I make the cutting iron A. in all respects 'inthercommou form-With anelongated slot, a, for the movement of the screw s, and with a circularaperture, 0, for the screw-head to pass through. Instead of insertingthe screw in the cap, I make the nut n, which may be in any convenientform, square, oblong, circular, or otherwise; but I consider the oblongform the best, because best calculated to hold the cap straight with thecutting iron. In the cap C I make the slot or opening z, into which thenut n is made to tit, and it should be so made as to receive the nutwith a snug joint. By this means the capG, which in other respects ismade in the common form, is readily adjusted by4 means of the screw andthe irons, separated byslipping the cap Coil` from the nut u.

What I claim as myinvention, and desire to secure by Letters Patent, is-

The nut n, in combination with the planing iron A, the screw s, and thecap C, made` and operated sul stantially as and for the purposesdescribed. l

I also claim the slot hin the cap C, when madel to lt upon lthe nut u,and applied to planing irons, substantially as described.
